Urban particles shape climate by influencing clouds and radiation. Vertical monitoring reveals overlooked impacts.

A recent study has uncovered compelling evidence suggesting that the climate effects of new particles in urban areas have been significantly underestimated.

Particle sizes are determined by the mechanism through which the particles enter the atmosphere. For example, homogeneous nucleation, in which a new particle is formed directly from the gas phase ...

Something “really strange” could indicate that someone somewhere on earth is attempting solar geoengineering: injecting gases or tiny particles into the upper part of the atmosphere to reflect ...

Traveling by boat for 17 hours, the team headed to a place called Svalbard and launched a small rocket — named Endurance, ...

The Scripps O 2 Program measures changes in atmospheric oxygen levels from air samples collected at stations around the world. CAICE is a Center for Chemical Innovation focused on the fundamental ...

Atmospheric ... effects limit our knowledge about climate change. Aa Aa Aa What is the source and composition of the aerosols? Atmospheric aerosols are suspensions of liquid, solid, or mixed ...

researchers have long suggested using tiny particles, or aerosols, that reflect the sun's rays back into space. Injecting these aerosols into the stratosphere — the layer of Earth's atmosphere ...

NASA launched its PACE climate satellite with the Dutch aerosol instrument SPEXone onboard. A full year of observations now ...
